The Dow Jones industrial average fell 96.46 points, or 0.86%, to 11,120.04, with Hewlett-Packard (HPQ ) leading the retreat. The broader Standard & Poor's 500 index was down 13.54 points, or 1.03%, to 1,295.5. The tech-heavy Nasdaq composite slid 22.15 points, or 0.94%, to 2,339.02.

Investors were assessing a key labor market gauge Friday. The Labor Department said nonfarm payrolls rose 211,000 in March after a downwardly revised 225,000 increase in February. The unemployment rate slipped to 4.7% from 4.8%. The data are fairly close to expectations and suggest a solid jobs market, says Action Economics.

The report comes amid concerns over Treasury yields, oil prices and the Fed, some analysts note. "This is kind of a mixed bag," says Chris Johnson, managing quantitative analyst at Shaeffer's Investment Research. "The selling is probably investors just taking profits before the weekend right now, and likely to be contained."

The underlying numbers, while strong, weren't as strong as some feared. "Overall, it's a benign report," says Brian Gendreau, investment strategist at ING Investment Management. "It looks pretty good for the economy, and it looks pretty good for the outlook for markets."
